If I could give this review, zero stars, I definitely would. I am extremely unhappy with the whole experience I’ve had with the seller, which is woot. They have no experience in selling products. They attach fake serial numbers on items that they shipped to you and when you tell them, you have a problem they are of no assistance. I am extremely infuriated with the quality of this product. I spent a lump sum amount of money on this now piece of junk. Oh, and to add my house almost caught on fire because the product overheated. I do not recommend anybody buy from the seller. The functionality is terrible. I am going to spread the word to everybody about my experience.
